Color transform of 1 10-5 M of DTITPE inside the presence of several anions (a) in THF resolution, Figure 8. Color adjust of 1 10-5 M of DTITPE in the presence of a variety of anions (a) in THF solution, and on silica gel strips below (b) ambient light and (c) UV irradiation (254 nm). and on silica gel strips beneath (b) ambient light and (c) UV irradiation (254 nm).4. Conclusions four. Conclusions In conclusion, the molecular sensormolecular sensor DTITPE and completely characterized. characterized. In conclusion, the DTITPE was synthesized was synthesized and completely In the presence of fluoride ions, a colorless solutioncolorless solution of DTITPE quickly turned yellow In the presence of fluoride ions, a of DTITPE right away turned yellow and from a Job’sand from a Job’s plot experiment, a 1:1ratio among DTITPE and F – DTITPE and F- ion plot experiment, a 1:1 stoichiometric stoichiometric ratio among ion was determined.was determined. These final results arethe formation of the formation of a species containing a These results are consistent with consistent using a species containing a hydrogen bond between the imidazole proton of DTITPE andof DTITPE and theafluoride ion, a conclusion hydrogen bond amongst the imidazole proton the fluoride ion, conclusion which was supported by NMR spectroscopic outcomes and DFT calculations.
